I was thinking about that, I'm gonna add it to the Trello board as a new idea.
Also the mod won't have "routes" by itself, it is a sandbox and it will adapt to the way player plays it, meaning that if you want to stay virgin just say no to any sex scene opportunity that involves the player, Sana will still love you so if you want her to cheat on you just allow male actors to approach her and let the cheating/harassment event run.
The same goes for the non-NTR path, you just gotta fuck her at every chance you got to improve the player's sex skill, make sure she is satisfied and stop any advances other male actors may have with Sana.
Basically what I'm trying to say is that there won't be a choice that will make her instantly to start cheating on you and activate the "NTR route" in which you won't be able to get to another route or whatever.
Also, in the final version (not test releases), when starting a new playthrough, you will be asked to "create" the player you want to play with, this goes from setting the penis size and its sensitivity to personality traits like sex skill, cuck, cheater. Note that there won't be conflicting traits, meaning that you can max out the cuckold trait and max out the sex skill too, making you the man that probably fucks best in the game (you won't have any trouble making any girl cum) but a cuckold too.
The idea of having the secret NTR makes more sense since in the vanilla game, as the player, you have to go to every sex event for it to be executed, which makes it contradictory that the player doesn't know that he is getting cucked by Sana since he is there too. Having it activated will make the experience feels realer, so I will probably implement this on the final version.
On a different note, I have added a in-game console to the game, yup you guessed it, another thing that was not planned for v0.2 but it is already done
More commands will be added and you will be able to tweak pretty much anything in the mod, from an actor body part size or personality trait to relationships between actors, so I guess there is no need to add an item in-game (like a cheat book or smth) since you can do it with the console.
This will help me greatly debug the game and you all too since you can tweak the mod by just using a few commands to your liking anytime (video below testing some commands)
